Will the Baltimore vs Boston game go to extra innings?

Prediction market odds and sportsbook odds often diverge because they serve different purposes and audiences. Sportsbooks set odds to balance their book and manage risk, while prediction markets reflect aggregated trader beliefs about true probability. This market may show a different implied probability than traditional sports betting venues, since traders here are motivated by accuracy rather than payout ratios. Comparing the two can reveal where the crowd sees value or where consensus differs from bookmaker pricing.
